Windowing in .NET Web Parts

We are writing web parts using .NET. Does anyone know how toreference the parent window of the web part? We need to know how toforce the display into the same IE session instead of opening a newwindow? We want windowing/sessions to work the same as a quick linksweb part works, i.e., when you click on a link, you do not haveanother instance of IE open in your task bar. It opens in the samewindow with an active back button to return to the previous window.

If we remove the piece of .NET code that opens a new window, ofcourse the display goes within the web part itself. This is OKsometimes, but in a of cases we need the full window. We're tryingto limit the number of IE sessions in the task bar.
